What is the difference between a motor starter and a contactor?
Motor started will have overloads the contactor connect es line voltage.
Working principle of servo motor?
Servo motors are geared DC motors with the closed-loop circuitry incorporated within them. The basic configuration of a servo motor composed of a DC motor, gearbox, potentiometer and control circuit.DC motor is used to move a gearbox with a large reduction ratio. The final shaft imposes a force on the external load and simultaneously acts on the axis of the feedback potentiometer. So, the potentiometer senses the position of the axis and sends a corresponding voltage to an operational amplifier. This voltage compared to the input voltage, that determines the desired position of the shaft, producing a voltage in the output of the comparator. This voltage powers the motor such that the shaft moves in the necessary direction to align with the angle that corresponds to the voltage applied to the input.
How does a frequency drive work?
Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
How do run 380V motor in 440V supply voltage?
You can use a voltage regulator IC/transistor that can take any input voltage (to a point) and spit out whatever voltage you want, depending on your application (in this case 380 volts) then be sure you build a regulator with the correct IC/transistor. Hope this helps!

Open loop systems in the home?
Open loop control systems are one in which Output have no effect on input. Toaster,Washing machine and a Dc motor are the examples. Consider an example of a dc motor, Due to voltage input it rotates a Shaft what happen if the load on shaft increases ???do you get the same output on same input??not possible because there is no such mechanism involved that will tell the motor to increase its input...that is no feedback mechanism involved in open loop system..thats why you will get a decrease in Output.
What are the 3 quantities that may be considered as parameters in order to change the speed of a dc motor?
The three quantities that can be adjusted to change the speed of a DC motor are the voltage applied to the motor, the strength of the magnetic field within the motor (field flux), and the load on the motor. By varying these parameters, the speed of the DC motor can be controlled efficiently.
What is the voltage tolerance of a standard electric motor?
the voltage tolerance of a standard electric motor is
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
Can an air conditioner unit running on 250 volts be run directly by 120 volts?
No, the unit has to operate on the voltage specified. The internal controls are all designed to operate on a 240 volt input. The motor in the air conditioner will not operate at the lower voltage and without this compressor motor operating the unit will not get cold.
What will happen to a motor if it is supplied with lower voltage than its rated voltage?
The amperage to the motor will go higher.
